CEM-KOTE FLEX CR is designed for waterproofing, repair, and protection of concrete structures exposed to hydrogen sulfide environments. It is used in concrete restoration in thin sections where superior flexibility, chemical resistance, and breathability are required. It is a highly flexible, fiber-reinforced, hydraulic-cement-based material with superior flexibility, resistance to hydrogen sulfide environments, crack, freeze/thaw, and vermin resistance, excellent bond and self-curing characteristics, and low shrinkage.
